    摘要: A method of depositing material onto a substrate at cryogenic temperatures using beam-induced deposition. A precursor gas is chosen from a group of compounds having a melting point that is lower than the cryogenic temperature of the substrate. Preferably the precursor gas is chosen from a group of compounds having a sticking coefficient that is between 0.5 and 0.8 at the desired cryogenic temperature. This will result in the precursor gas reaching equilibrium between precursor molecules adsorbed onto the substrate surface and precursor gas molecules desorbing from the substrate surface at the desired cryogenic temperature. Suitable precursor gases can comprise alkanes, alkenes, or alkynes. At a cryogenic temperature of between −50° C. and −85° C., hexane can be used as a precursor gas to deposit material; at a cryogenic temperature of between −50° C. and −180° C., propane can be used as a precursor gas.

    摘要: A cathode ray tube comprising an electron source and an electron beam guidance cavity having an input aperture and an output aperture, wherein at least a part of the wall of the electron beam guidance cavity near the output aperture comprises an insulating material having a secondary emission coefficient &dgr;1 for cooperation with the cathode. Furthermore, the cathode ray tube comprises a first electrode which is connectable to a first power supply for applying, in operation, an electric field with a first field strength E1 between the cathode and the output aperture. &dgr;1 and E1 have values which allow electron transport through the electron beam guidance cavity. The cathode ray tube further comprises a conventional main lens to obtain a spot on a display screen. According to the invention, an electron lens is placed between the exit of the cavity and the main lens for directing the electron beam at a predetermined angle towards the entrance of the main lens.

    摘要: A particle optical apparatus, such as an ion implantation apparatus, an Auger electron spectrometer, an XPS analysis apparatus, and the like, is provided with a radiation source by means of which a wafer or substrate brought into the apparatus can be bombarded by radiation providing for at least a positively charged surface layer of the wafer or substrate. The apparatus further comprises a charge neutralization device with means for providing secondary electron emission and transport means for transporting secondary electrons. This transport means device is provided with a hollow insulating structure for controlled electron transport based on secondary electron emission, particularly in the form of an electron fibre with electrodes at the entrance and exit. The exit of the electron fibre forms a clean secondary electron source.
